Any point in waiting for the SHA-3 standard?
The Wikipedia article on SHA-3 says that Keccak has been chosen but the standard hasn't been issued. Does this matter?
That is, can we just assume it's going to be as specified by the submitters ...

Why are the constants so simple in Keccak?
Keccak, the construction selected for SHA-3 is very interesting. It seems unlike other primitives and has chosen very simple constants. (Keccak talk PDF)
The initial values of the state in Keccak is ...

What security does Keccak offer against quantum attacks, specifically Grover's algorithm?
In the face of non-quantum attacker, Keccak[r=1088,c=512] with 512 bits of output provides:
Collision resistance up to $2^{256}$ operations
Preimage resistance up to $2^{256}$ operations
Second ...

Does Keccak have an eTCR mode?
On page 7 of NIST's views on SHA-3's security requirements and Evaluation of attacks, I see that, at least at this point, NIST planned on offering SHA-3 having eTCR security (defined on page 3):
...
